I found this book to be very well produced and very helpful. However, It is decribed repeatedly as 'Celtic'. Lindisfarne, im sure most people will be aware, is part of England and most certainly was part of England when the Lindisfarne Gospels were created (698-715), in the period that is known as 'Anglo-Saxon' England.
I understand that Insular art is widley and wrongly referred to as 'celtic' art, and for that reason this book will be found under the 'celtic' heading, but misinformation is misinformation. This is English art and should be celibrated as such.
